CVA (Cerebral Vascular Accident, Stroke).

A CVA can be due to ischemia caused by blockage (ARTERIAL thrombosis, ARTERIAL embolism), or a hemorrhage. Diagnostic imaging can identify the cause.

Coding Instructions

Co-code with TPA if applicable

Don't forget to code Thrombolytic Infusion (STROKE) if TPA actually administered to the patient in the ER prior to coming to your unit or while if given while in your unit.

Question: cause vs outcome

• Are we concerned more with causes or diagnostic codes for CVA or the physiological outcome? Many CVAs have temporary weakness resolved post t Pa-versus dense hemi-paresis and as mentioned above diaphragmatic impacts-perhaps sub-coding is not so irrelevant when looking at patient rehab requirements or long-term care dispositions?--Llemoine 08:12, 2016 October 7 (CDT)
  • Are you asking about how you might change coding? I don't understand where you are going... Ttenbergen 14:54, 2016 October 12 (CDT)

CVA secondary to Arterial blockage

• If a patient is coming in with a CVA secondary to an arterial blockage code as 50500 -CVA-Cerebral Vascular Accident. Do not code this as a venous CVA.

Incidental findings of OLD lacunar infarcts

• Dan Roberts:Incidental findings of “old lacunar infarct” on CT will continue to be included as COMORBID diagnosis. Staff have been including them as comorbids, if we stop including then this will affect the overstay project that is currently being piloted at the Grace and will eventually be done at other sites in the Region. -Trish Ostryzniuk 10:52, 2012 September 14 (CDT)

eliminate code?

• 50508 - CVA-Brainstem is really the same as code 504. This was an unintended double code that crept into list ages ago.Trish Ostryzniuk 16:05, 2012 July 12 (CDT)
  • Should we delete one of them from the drop-down? if so, please add to Requested CCMDB changes for the next versionTtenbergen 09:37, 2012 September 13 (CDT)Ttenbergen
    • By now we are not changing dx codes and waiting until ICD10 so I took out the discussion template. Ttenbergen 09:39, 2016 October 13 (CDT)

Wording changed for 50507 to cerebral venous thrombosis to include all cerebral venous thrombosis. Discussed at the task meeting August 21,2014. http://emedicine.medscape.com/article/1162804-overview
